Abstract: In an apparatus for analyzing a layout of a document, a character candidate element generator generates character candidate elements from black pixel linkage components of a document image. A horizontally oriented line rectangle generator sets a plurality of character candidate elements as a line candidate rectangle, among character candidate elements aligned in horizontal line orientation, when each amount of displacement of the set character candidate elements in a vertical orientation with respect to the horizontal line orientation, is smaller than or equal to a threshold value. A horizontally oriented paragraph-box generator sets a plurality of line candidate elements having approximately the same length as each other in the vertical orientation, as a paragraph candidate element.

Abstract: The present invention as disclosed hereby is to provide an apparatus and method for allowing images to correspond to each other and a program therefore to automatically perform or make synchronous correspondence of images. According to the apparatus on the condition that there are OHP files and a moving image photographing a lecture or the like using such OHP files, resemblances between the OHP files and OHP image regions of frame images constituting the moving image is calculated such that the correspondence processing between the OHP files and the frame images can be performed based on the calculated resemblances.

Abstract: In a structure in which a rotating bezel is mounted on a case body, the present invention provides the structure which permits the rotating bezel to be mounted and removed without difficulty even if a brittle material and a deformation difficult material is used in the rotating bezel. When the rotating bezel 25 is pushed downward, the lower end of the engaging rib 25a of the rotating bezel 25 is abutted against the upper end of the holding rib 21d of a glass fixing ring 21 and stress is applied thereby so that the elastically deformable section 21b of the glass fixing ring 21 is elastically deformed inward, that is, toward the side where a clearance is formed. As a result, the engaging rib 25a goes over the holding rib 21d and the rotating bezel 25 is kept in a held state as shown in the figure.
